The question shouldn't be if what needs to be done can be done with a
combination of @class and CSS, but rather if it add meaningful
semantic information. Most of the elements in HTML could be replaced
with <div> elements and @class to set their style. The reason that is
done is because <table> carries richer semantics than <div
class="table">.

So, the question is, does code/@type add meaningful information
without contributing to element/attribute overload?

I would say yes.

I see <code> as being somewhat similar to <style>. The difference
being that <code> is displayed but not executed while <style> is
executed but not displayed. The @type attribute on <style> elements
carries the information of what language the contained code is in.
This is used by the browser to know what parser should be used, but
can be used by other things as well.

The reason that people don't shove the mediatypes of their code into
@class attributes is because there is no standard way telling people
to do it. (or even that they should) If we add a @type attribute to
<code>, we'll start to see more people use it.

If all my <code> blocks are marked up appropriately, I could easily do
searches for snippets of code in my posts in javascript. (//code[@type
= "text/javascript"])
